Forging: 4340 steel is usually forged at a temperature of 1065 to 1230 °C (1950 to 2250 °F); after forging, the parts can be air-cooled in a dry place, or preferably with a furnace. Welding of AISI 4340 Steel. AISI 4340 steel has good weldability. It can be easily gas or arc welded, but electrodes of the same composition should be used.

MOHS Hardness Scale For Gemstones. The MOHS Hardness Scale starts with talc at 1 being the softest mineral and ending with diamond at 10 being the hardest mineral. It is universally used around the world as a way of distinguishing minerals. Simply put: the higher the number, the harder the mineral. The MOHS scale was created by trying to ...

Measuring gemstone hardness can be tricky. Often, a mark that looks like a scratch is actually a trail of powder left by the supposedly harder material! Fractional hardness scores, like 5.5, are reported when the literature has indicated an intermediate value. However, it's really not critical whether the hardness of a mineral is 5 or 5.5.
Hari om, you are asking a question as to :"What is heavier, steel or iron?". Hari om. ANSWER : You can compare weights of materials based on their densities or specific gravities. Density is defined as the mass per Unit Volume. Specific gravity is...

A913 is a high-strength low-alloy steel for structural shapes, produced by the quenching and self-tempering (QST) process. It is intended for the construction of buildings, bridges, and other structures. Four grades provide a minimum yield point of 50 to 70 ksi.
They possess a face-centered cubic (fcc) microstructure that is nonmagnetic, and they can be easily welded.Type 304 stainless steel (containing 18%-20% chromium and 8%-10.5% nickel) is the most common stainless steel. It is also known as "18/8" stainless steel because of its composition, which includes 18% chromium and 8% nickel.
Drill bit cutting speeds are very important in the drilling of metals. Drill speed becomes increasingly important when drilling harder metals. You should use a cutting speed chart to ensure you drill in the most efficient manner possible. We have produced speed and …
5 0 6 3.1 Carburising Stainless steels can be carburised to im-prove surface hardness and resistance to galling. During the carburising process, the carbon atoms diffuse through the surface at high temperatures and have the affinity to react with the chromium present in stain-less steels. They can form chromium carbide (Cr 23C 6). This process ...
The archetypal duplex alloys contain 22-23Cr, 4.5-6.5Ni and 3-3.5Mo wt%, representing some 80% of all duplex stainless steel use. Detailed compositions are given in Table 4. A significant application is in the production of tubing in corrosive oil and gas wells; such tubes have been installed particularly in …

It is clear from Table 3 that the use of cast iron or mild steel can only be contemplated in pumps operated occasionally. From data in Table 3, Ni-Cu alloys 400 and K-500 and stainless steel Type 316 have very high resistance to flowing seawater, and cast versions of these alloys are preferred for pump impellers.
When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron(one millionth of a meter) is used.
When using >B< Press Stainless Steel fittings, the application parameters in chapter 2 must be observed. >B< Press Stainless Steel fittings can be used with all stainless steel tubes that comply with AS 5200.053 Series 2. The use of different materials in a drinking water system must comply with the appropriate codes of practice.

One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond). Most abrasives that effectively achieve an anchor pattern on a surface have a Mohs' hardness of at least 6.0. Mohs'. The Mohs' scale of hardness, devised by ...
